This invention relates to improvements in flyer devices and moreparticularly to a novel flyer cap adapted to permit the use of readilyreplaceable flyer wires.

5 Hitherto, it has been proposed to use wooden and brass flyer blocksfor the mounting of the customary flyer wires. In the use of theseconstructions, it has been necessary to thread the wires in and upon thewooden 10 blocks and then form the arms and eyelets after such threadingoperation. .:VVhen the flyer wires wear out, as they usually do aftertwo or three weeks operation, it is necessary, either to throw away theflyer block or to re- 15 move it from the machine and rewire it.

This latter, as indicated above, is an expensive and time-consumingjoband does not permit of any savings in' operating time, it beingnecessary to keep a duplicate set of blocks in order to prevent shuttingdown of spindles when breakage of the wires occurs.

It is an object. of the present invention to provide a novel flyer capadapted to operate with wooden and brass flyer blocks.

It is another object ofthis invention to provide such an improved capwhich is so constituted and arranged as to permit the use of readilyreplaceable flyer wires with wooden and brass flyer blocks, of the abovedescribed type.

Another object of this invention is the provision of the improved woodenflyer block having a novel flyer cap adapted to retain replaceable flyerwires in position without the h "f use of a mill nut.

These and other desirable objects and advantages of the presentinvention will be described in the accompanying specification andillustrated in the drawings, certain preillustration only, for, sincethe underlying principles may be embodied in other specific mechanicaldevices, without departing from the spirit and scope of the presentinvention,

. it is not intended to be limited to the forms ferred embodiments beingshown by way of Fig. 1 is a vertical section of a flyerblock having anoffset portion adapted to engage a bobbin bushing and being providedwitha novel flyer cap;

Fig. 2 is a View similar to Fig. 1, showing showing means for retaininga plurality of flyer wires.

Fig. 1 is a view similar to Fig. 3 showing means for retaining a singleflyer wire Referring now to the. drawings, there is shown in Fig. 1 theusual bobbin 1 mounted on .a spindle 2. The latter is uniform ,indiameter and its upper portion in adapted to receive a flyer'block 3.having anolfset lower portion 1 adapted to engage flange 5- of thebushing inserted in the-bobbin. v At its upper end the member 8 isprovided with a hub portion 6 having a central groove 7 and a bearingsurface 7a adapted to receive the usual hump or central half roundportion of a flyer wire 8 having the usual eyelet 9 and dependingarm Aflyer cap 11' having a plurality of apertures 12 and 13oppositelydisposed with respect to each other block. In operation, theflyer block is in serted in the bushing 5; of the bobbin 1 and ment withthe underside of the member'5. A flyer wire 8 having a central portionadapted to'engage channel 7 and abutting against section 7a as a bearingsurface is inserted in pos'ition,..the flyer cap is next lowered intoposition'over the hublfi of the,

'at the one edge thereof, and a central a'per ture 14 adapted forengagement withj'the hub 15 of member 3 is slipped overtheflyer block.The arms 8 of the flyerwire are bent away from thecentral portionthereof which is in abutment against the bloc lng until the. 5 saidarms, engage the slots 12 and/or 13 of the said caps being. held inposition thereby and serving to tense the flyer wires in place.

,In the modification shown in Fig. 2, the

- usual bobbin 1 is mountedon a spindle QO pending arms 24: and threadengaging eyelets 25 as well as the usual central portion engaging theslot 22 in the flyer block. A flyer cap 26 similar in construction tothe one previously described and configured to the shape of the block,is fitted over the block and the wires sprung into engagement with theslotsl2 and/or 13. As above noted, a plurality of flyer Wires may bemade use of, where desired, by the simple expedient of using the pair ofdouble slots 12, rather, than the pair of single slots 13; For easymanufacturingand to avoid duplication of parts,

the two series of slots 12 and 13 may be formed in a single device,either set being used at will by the operator.

The novel flyer cap and block assembly of the present invention ischaracterized by extremely low cost of manufacture, due to the fact thatthe wooden blocks may readily be formed by automatic machinery and theflyer caps may be stamped or pressed out from sheet metal of suitablethickness.

It will now be appreciated that there has been provided a plurality offlyer block constructions in which a unitary flyer cap of sheet-metalor.other like construction and of suitable size and configuration isadapted to be used and thus permit the use of replaceable flyer wireswithout requiring dismounting or removal of the flyer blocks from theirrespective spindles.

In accordance with the provisions of the patent statutes, I havedescribed the principle'sof operation of my invention, together with thedevice which I now consider to represent a preferred embodiment thereof;but I desire to have it understood that the device shown is onlyillustrative of the basic concept of the present invention, and that thesaid invention may be carried out by other means.

- I claim:

1. A flyer including an apertured body having an offset flange at thebottom, a head portion having an annular peripheral groove, a. flyerwire disposed in the groove. and a separable cap fitted over said head.

2. A flyer including an apertured body having an offset flange at thebottom, a head havin an annular peripheral groove, a flyer wire disposedin the groove, a separable cap fitted over said head, and means in thecap for tensioning the flyerwire.

3. A flyer including an apertured body having an oflset flange at thebottom, a head havingan annular peripheral groove, a'flyer wire disposedin the groove and abutting thereagainst, a removable flyer cap fittedover said head, means inthe cap for tensiorr' ing the flyer wires, saidmeans including slots in the skirt of the cap.

4. A removable flyer cap including a skirted body portion and anapertured top portion, said skirt being provided with a plurality ofwire engaging slots.

5. A removable flyer cap including a skirted body portion and anapertured top portion, said skirt being provided with a plurality ofopposed wire engaging slots.

6. A removable flyer cap including a skirt and an apertured top, andreentrant slots in said skirt.

7;. A removable flyer cap including a skirt and an apertured top, andreentrant slots n said skirt adapted to receive flyer wires.

8. A-removable flyer cap including a skirt and an apertured top, and aplurality ofreentrant slots in said skirt.

9. A flyer including an apertured body of fibrous material, an annularperipheral groove in said body, a flyer, w re disposed in sald groove,and a flyer cap on sa-idbody and in tensioning relation with said wire.

10. A flyer including an apertured body of fibrous material, an annularperipheral groove in said body, a flyer wire disposed in said groove,and a separable flyer cap on said body and 1n tens omng relation withsaid wire.

11. A flyer including ,an apertured ;body of fibrous material,ianhannular peripheral groove in said body, a flyer wire disposed insaid groove, and a manually removable flyer cap on said body and intensioning relation with said wire.

Inltestimony whereof 'I aflix my signature.
